Scanning barcodes at checkout time is now commonplace even in small stores. Clay Critters provides a free barcode ticketing service to any retailer who uses a point-of-sale system (POS).
We generally use the standard 12-digit UPC-A barcode styles, although we have permission to print the space saving, 6-digit, zero-suppressed UPC-E style reserved for companies selling small products.
The 12-digit unified product codes (UPC) barcode consist of three portions, the company code (first six digits), the product stocking code, or SKU (next five digits), and finally a checksum digit to verify that the scanner read the barcode correctly. Clay Critters’ company code is 093300 and is registered with the Uniform Code Council (UCC), so there is never a possibility of a misread or mischarged code from us.
All of our barcodes are printed in-house using a Zebra-4M barcode printer. We never have to wait for a label shipment. This high-contrast printer is unique; instead of printing round dots, like your laser printer and FAX does, it prints square dots, which make the barcode bars crisper and more accurately scanned.
